LT8580HDD#PBF

Overview

The LT8580HDD#PBF is a synchronous boost, SEPIC, and inverting DC/DC converter IC manufactured by Analog Devices Inc. It operates with an input voltage range of 2.9V to 40V and supports adjustable output voltages from 1.2V up to 65V at the switch node. The device delivers a maximum switch current of 1.2A and features a programmable switching frequency between 200kHz and 1.5MHz. It utilizes an 8-lead DFN package with exposed pad for surface mount installation.

Feature Summary

Supports multiple topologies including boost, SEPIC, and inverting configurations within a single integrated circuit.
Features synchronous rectification to enhance conversion efficiency across various operating modes.
Includes internal soft-start functionality to manage inrush currents during power-up sequences.

Applications

Industrial control systems requiring flexible voltage regulation
Automotive electronics utilizing wide input voltage ranges
Battery-powered devices needing efficient step-up or inversion capabilities

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging rather than tape and reel when ordering. Confirm that the DD variant corresponds to the 3x3mm DFN footprint required for your PCB layout. Ensure compatibility with the 8-lead pinout configuration before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require both positive and negative outputs or complex topology flexibility. Consider the 1.2A switch current limit against peak load requirements. Evaluate the thermal performance of the exposed pad DFN package for your specific ambient temperature conditions.

Part Context

This part belongs to the LT8580 family of high-efficiency switching regulators. It shares core architecture with variants like LT8580EMS8E but differs in package type. The family is designed for applications demanding high power density and flexible voltage conversion options.

Replacement Considerations

LT8580HDD#TRPBF offers identical electrical characteristics but comes in tape and reel packaging instead of tubes. Other LT8580 variants may share functional similarities but differ in package dimensions or thermal properties.
